DETAILED DESCRIPTION

This invention relates to a bathtub insert configured for fitting within an existing bathtub and utilizing an existing shower head. The bathtub insert provides a deeper and more convenient bathing facility within the confines of a generally conventional installed bathtub or shower stall. The insert forms a deeper tub relative to the existing tub and the insert walls extend higher than those of the existing tub. The insert includes a seat formed therein and is sized to fit within the existing tub or shower stall. In one embodiment, the insert includes fixed walls and a sealing pivotal door. The door allows a disabled or elderly person to more easily enter and exit the bathtub by sliding onto the seat. In a further embodiment, the walls may be telescoping or include a pivotally connected upper section.

The water level is raised within the insert such that a person may sit on the seat and take a bath. The insert does not require any additional plumbing as the water supply may be provided by the existing shower head or bathtub faucet. In one embodiment, the insert includes a drain for draining water from the insert.

In one embodiment, the insert is positionable in two different orientations. In a first orientation, the insert defines a shower seat for a user. In a second orientation or inverted position, the insert defines an easily accessible bathing area for a user, including a seat and access door.

FIGS. 1A, 1B, 2A, and 2B illustrate a bathtub insert 10 according to one embodiment of the invention. The bathtub insert 10 provides an easily accessible and deeper bathing area than conventional bathtubs. The bathtub insert 10 is configured for use with a conventional bathtub or shower stall. In the illustrated embodiment, the bathtub insert 10 may be positioned in a bathtub (not shown) in a first orientation for use as a shower seat (FIGS. 1A and 1B) and in a second orientation (FIGS. 2A and 2B) for use as a deeper bathtub.

Referring to FIGS. 1A and 1B, the bathtub insert 10 includes a first end wall 14, a second end wall 18, two side walls 22, 26 extending between the end walls 14, 18, and an upper wall 30. As will become clear in FIGS. 2A and 2B, the insert 10 does not include a lower wall. A seat 34 is defined between the first end wall 14 and the upper wall 30. The seat 34 includes a sit portion 34A extending generally inward from and substantially perpendicular to the first end wall 14, and a seatback portion 34B extending generally downward from and substantially perpendicular to the upper wall 30. In the illustrated embodiment, the sit portion 34A of the seat 34 is about 21 inches above a lower edge 14A of the first end wall 14 and recessed from the upper wall 30 about 15 inches. The seat 34 provides a sitting area for a user when the insert 10 is positioned in the first orientation, and allows a user to sit down while taking a shower. The sit portion 34A supports the user's posterior and the seatback portion 34B provides a backrest for the user.

The bathtub insert 10 includes a pair of generally L-shaped rails 38 positioned adjacent the seat 34. Each rail 38 includes a first end 38A mounted proximate the intersection of the upper wall 30 and the respective side wall 22, 26 and a second end 38B mounted proximate the intersection of the first end wall 14 and the respective side wall 22, 26. As shown in FIG. 1A, the second end wall 18 of the insert 10 includes a door 42 for providing access to a bathing area 46, as discussed below.

Referring to FIGS. 2A and 2B, by inverting the bathtub insert 10 (i.e., rotating the insert 10 approximately 180°) to the second orientation, the bathtub insert 10 provides the bathing area 46 for a user. In the second orientation, the upper wall 30 and the rails 38 of the insert 10 define a base surface that rests upon a bottom of the bathtub for supporting the insert 10. The walls 14-30 of the insert 10 define the bathing area 46 with an open end for gaining access to the bathing area 46 and supplying water to the bathing area 46. In the illustrated embodiment, the end walls 14, 18 and the side walls 22, 26 of the insert 10 extend higher than walls of the existing bathtub to define a deeper bathing area 46 than the existing bathtub.

The door 42 formed in the second end wall 18 of the insert 10 provides access to and from the bathing area 46 of the insert 10. The door 42 allows a user to easily slide or step into the bathing area 46 from the bathtub, shower stall, or bathroom. In the illustrated embodiment, the door 42 has a height of about 21 inches and is spaced from the upper wall 30 (i.e., begins above the upper wall in FIGS. 2A and 2B) by about 15 inches. Preferably, the door 42 is sealed such that water within the bathing area 46 (see FIG. 2B) does not leak from the insert 10.

In one embodiment, the door includes a dagger board inserted into a groove slot formed in the second end wall surrounding the door opening. In another embodiment, the door includes a hinged door that folds by a hinge and opens outwardly with respect to the bathing area. The hinge may be molded in plastic as a live hinge or metal and attached to the door and insert in a conventional manner. Both doors include grommet material to secure a seal to the inner or outer periphery of the door opening. In still another embodiment, the door includes a hinged door coupled to an interior surface of the insert (i.e., the second end wall). The door is larger than a width or a length of the door opening and is creased in the middle, similar to a folding door. The door includes a seal (e.g., formed from rubber or plastic) positioned about the inner or outer periphery of the door opening.

Referring to FIG. 2A, the sit portion 34A and the seatback portion 34B of the seat 34 (when the bathtub insert 10 is in the first orientation) define a second seat 50 when the insert 10 is in the second orientation. The sit portion 50A of the second seat 50 may be used as a seat to support a posterior of the user while bathing or a step, while the seatback portion 34B extends generally parallel and adjacent to the user's legs while the user is seated. In the illustrated embodiment, the second seat 50 is raised about 15 inches from the upper wall 30 of the insert 10. The upper wall 30 of the insert 10 includes a closeable drain 54 for allowing water to drain from the bathing area 46.

In one embodiment, the bathtub insert 10 is fabricated from aluminum. In another embodiment, the insert 10 is fabricated from a plastic material using an injection molding process, a roto-molding process, or the like.

The insert 410 is shown in a telescoped position in FIGS. 6 and 7. A conventional bathtub has a depth of about 12 inches; however, in the illustrated embodiment the telescoping insert 410 provides a bathing area 414 having a depth of about 36 inches.

The bathtub insert 410 includes three generally rectangular portions that are slidably coupled together in a telescoping relationship. A lower portion 418 provides a base for the insert 410 and is positioned within, on, or around the existing bathtub (not shown). In the illustrated embodiment, the lower portion 418 includes a seat 422 for a user to sit on or step on during use. A central portion 426 is slidably coupled to an exterior surface 418A of the lower portion 418 and an upper portion 430 is slidably coupled to an exterior surface 426A of the upper portion 430. In one embodiment, seals are positioned between the coupled portions 418, 426, 430 to prevent water leakage. When the insert 410 is in a compacted position, the lower portion 418 is retained within the central portion 426, which is retained within the upper portion 430.

To move the insert 410 to the telescoped position for use, the upper portion 430 is lifted generally upward to pull the upper portion 430 and the central portion 426 away from the lower portion 418 and create the deeper bathing area 414. The three portions 418, 426, 430 thereby define the bathing area 414 for a user. Locking means (not shown) may be used to hold the insert 410 in the telescoped position. Water is supplied to the bathing area 414 from a shower head or bathtub faucet. In one embodiment, the lower portion 418 may include a closed bottom for holding water within the bathing area 414 and a closable drain for draining water from the bathing area 418. In a further embodiment, the lower portion 418 includes an open bottom.
